Online Casinos By Software
Every casino review on this site names the software behind the casino, and it is the line most readers skip. It is worth more attention than it gets, and for different reasons than the industry usually gives. This page explains what a software name actually tells you, then covers each provider that appears on our reviews — including the ones that no longer exist, because a good number of them do not.
What the software name actually tells you
Who tests the games, and against what
The provider, not the casino, builds the random number generator and submits it for testing. A recognised provider has its RNG and its published return-to-player figures audited by an independent laboratory, and those results follow the games to every casino that licences them. This is the single most useful thing the software line tells you: an established provider has more to lose from a rigged game than any one casino it supplies.
Whether the games are actually different
Mostly they are not. Dozens of casinos licence the same platform and therefore offer the same slots under the same names with the same maths. If two casinos run the same provider, the meaningful differences between them are the licence, the banking and the withdrawal terms, not the game selection — which is why comparing lobbies is usually a waste of an evening.
Progressive jackpots are pooled across the provider
A network jackpot is funded by every player on every casino running that provider's games, which is why the figures get so large. It also means the jackpot is not the casino's to pay: it sits with the provider, and the casino's own withdrawal limits may still apply to getting it out.
What it does not tell you
It says nothing about whether you will be paid. A casino running well-tested games from a reputable provider can still hold withdrawals, apply punitive bonus terms or simply stop answering. Software quality and operator conduct are separate questions, and the second one matters more.
Providers still operating
Playtech
One of the largest suppliers in the industry, publicly listed and supplying regulated markets across Europe. Broad range across slots, table games and live dealer. Its presence is a reasonable signal that an operator holds a licence in a market Playtech is prepared to serve.
Real Time Gaming
Usually written RTG, and one of the few established providers still supplying operators that take United States players. Slot-heavy, with a recognisable house style and a long-running set of progressive jackpots. It appears on several reviews here for exactly that reason.
Rival Gaming
Also seen as Rival Powered. Another provider serving the United States market, best known for its i-Slots, which run a short narrative across the bonus rounds rather than presenting a single fixed feature.
Betsoft
A slots specialist known for heavily animated three-dimensional games. Its titles are widely licensed and turn up as part of a mixed lobby far more often than as a casino's sole platform.
Spinomenal
A newer slots studio with a large and fast-growing catalogue, supplied into mixed lobbies alongside other providers rather than powering a casino on its own.
Visionary iGaming
A live dealer specialist — real tables, real dealers, streamed — and one of the few live providers that has continued to serve United States-facing operators. Where a casino on this site offers live blackjack or baccarat to US players, this is usually what is behind it.
DGS
Digital Gaming Solutions, a sportsbook platform rather than a casino one: it handles odds, bet placement and settlement. It appears on the sportsbook reviews here rather than the casino ones. Confirm its current arrangement with any operator before treating a listing as up to date.
Providers that have been renamed or absorbed
Microgaming
Renamed. Microgaming was among the oldest names in online gambling and supplied a large share of the market for two decades. In 2022 its content business was bought out by its management and the company now trades as Games Global. The games and the jackpot network continue under the new name, so a casino described as running Microgaming is not misdescribed so much as described in the industry's older vocabulary — which includes most of the reviews on this site.
Net Entertainment
Acquired. Usually written NetEnt, and long one of the most respected slot studios in Europe. It was acquired by Evolution in 2020 and its games are now supplied as part of that group's catalogue. The brand survives; the independent company does not.
Cryptologic
Wound down. One of the true pioneers of online casino software, and the provider behind a generation of licensed-brand slots. It was acquired in 2012 and the brand was retired thereafter. A casino still listing Cryptologic is displaying a platform that has not been current for well over a decade.
Boss Media
A Swedish provider from the first wave of online casino software, best known in its day for poker and table games. It passed through acquisition and the brand is no longer marketed independently; confirm what a casino actually means by it before assuming the games are current.
Providers that have closed
Vegas Technology
Closed, and badly. Vegas Technology shut down abruptly in 2011, and the casinos running it went with it — players at a number of those casinos were left unable to withdraw balances. It is the clearest example on this page of why the software line is worth reading: when a platform fails, every operator on it fails at once. Any site still advertising it should be treated with considerable caution.
Progressive Gaming
Closed. Progressive Gaming International ceased trading around 2010 and its assets were broken up. The name survives only on old cashier and lobby listings.
Top Game
Gone, with a poor record behind it. Top Game supplied a group of casinos that attracted sustained complaints in the early 2010s, including disputes over game behaviour and unpaid withdrawals. It is no longer a going concern, and its appearance on any current lobby would be a reason to look elsewhere.
VueTec
An early live dealer streaming specialist, notable for broadcasting from real land-based casino floors rather than a studio. It has not been an active supplier for many years; confirm before relying on a listing.
Providers we cannot confirm are still trading
These appear on our older review data. We have not been able to establish that they are currently supplying operators, and we would rather say so than imply they are.
B3W Group
A small supplier of slots and casual games, present on a handful of lobbies in the early 2010s. Current status unconfirmed.
CGTV Games
A small provider from the same period, and one of the least documented on this list. Current status unconfirmed.
GameScale
A platform and games supplier aimed at operators wanting a turnkey casino. Current status unconfirmed.
Octopus Gaming
A supplier associated with United States-facing operators, appearing as part of a mixed lobby rather than on its own. Current status unconfirmed.
Parlay Entertainment
A bingo platform rather than a casino one, and for a period a significant supplier in that corner of the market. Current status unconfirmed.
Not a provider
Proprietary
Not a company — a description. It means the operator wrote the games itself rather than licensing a platform, and it cuts both ways. In its favour: the games are genuinely unavailable elsewhere, which is the one case where comparing lobbies is worth the effort. Against it: there is no independent provider whose reputation rides on the maths, so the testing and the return-to-player figures rest entirely on the operator and whoever audits it. Look for a named testing laboratory rather than taking the description on trust.
Which software the sites we review run
The distribution is lopsided, and it reflects the industry rather than our selection.
Fifteen of the casinos reviewed here run Microgaming, now Games Global — they belong to the same group and share a platform, a jackpot network and, in most respects, a lobby. Choosing between them on games alone is not a real choice; the licence, the banking and the terms are where they differ, and the banking methods page covers the second of those.
Real Time Gaming runs Everygame Casino and SlotoCash. Proprietary platforms power Slotland and Win A Day, which is why their games do not appear anywhere else. Bovada Casino is the most mixed lobby among the sites we review, combining its own proprietary games with Real Time Gaming, Rival and Spinomenal.
Software is also the fact most likely to have moved since a review was written: providers are bought, renamed and dropped more often than casinos change their cashier pages. Treat the name as a starting point and check the lobby itself.
Our guide to finding a safe online casino covers the licence and terms checks that matter more than the platform, and the not recommended list names the operators we will not send you to.
